Gents,
Thanks to Wolfgang DL4YHF, the grabber at m= y QTH is=20 now running a new beta version of Spectrum lab, that should stop the=20 problem of multiple users getting partial images.
After an initial rush of activity, the numb= er of=20 users has calmed down, rather as expected.
Feel free to jump on board and try to break= it=20 again!
The system is connected to my main antenna=20= but this=20 is at minimum height and not correctly matched. Still it works pretty well a= nd=20 many signals were visible last night.
I have also got the magnetic antenna workin= g,=20 (placed temporarily on the shed roof) and it will be re-mounted when the wea= ther=20 permits, it seems slightly better than the reduced height main=20 antenna.
 
I dont have the fantastically low noise flo= or that=20 John GM4SLV offers, but I hope to leave the grabber running for the duration= of=20 the UK experiment or longer, if it is considerd useful. It is far enough awa= y=20 from other grabbers to perhaps be of some use for the experiment. It is also= a=20 testing ground for possible similar systems at SHF giving 'inverse' beacons=20= for=20 propagation indication.
 
any comments or problems encounterd, please= let me=20 know!
